4 Claims.

This application is a continuation in part of my application for Apparatus for hoisting and distributing loose materials filed August 5, 1924,

Serial No. 730,161. In that application I dis- 5 closed and claimed a hoisting apparatus and distributing apparatus for concrete materials as Well as means for erecting such apparatus and other features.

The present improvements accordingly relate to so much of the aforementioned subject matter as pertains to the erection of mast plants and the method and means for accomplishing same. In the gravity distribution of loose materials of the type above mentioned and particularly in construction Work on buildings, bridges, etc., a mast plant is erected whereby the materials may be elevated to or adjacent the top thereof, and dumped into chutes for gravity distribution to the point of placement.

A plant of this character is described and claimed in my copending application and comprises a mast structure providing for the support of a traveling hopper or bucket on one side and a feed chute extending through the body of the mast itself for transporting material from the hopper directly to the work or to a suitable delivery spout or chute. The feed chute is movably mounted Within the mast framework so that said chute can be held or deflected out of the path of the traveling bucket and automatically restored to material-receiving position beneath the bucket when the latter has arrived at a discharging position.

While the present improvements are illustrated and described with the foregoing structure as a basis, it is to be understood that same is merely illustrative of the application of my invention, which is adapted for practice and use in connection with any type of sectional mast plant.

A primary object, among others, of the improvements, is to provide a novel method of erection of the mast or tower employed in plants of the aforementioned type. A further object is to provide novel means for practicing the method, including a minimum of parts, susceptible of ready and eicient operation. Such means may preferably include bracket members adjustably positioned on the mast and serving the two-fold purpose of providing a support for an erection pole in the construction of the mast or for supporting an adjustably positioned delivery spout in the operation of the apparatus. The erection means and support therefor on the mast may obviously take other forms; that i1- 1928, Serial N0. 313,679 l (Cl. ISB-16) lustrated being one embodim improvements.

Other features of the invention include novel details of construction and arrangement of parts, which are described or exemplified by Way of illustration in general, in the accompanying description and drawings in which a preferred embodiment of the invention has been selected for illustration.

Referring to the drawings for a more detailed description of the invention, a supporting mast M for the hoisting and distributing apparatus may be formed of steel with corner angle irons connected by latticing as shown, orA it'may be formed of Wood or of any desired combination of wood and metal. The mast'may be constructed 85 in sections to t' the height thereof to the lrequirements of the work, the sections being joined together at their abutting endsV by means of lconnecting plates such as are shown at 11 in Figure 4 of the drawings and described in particu- 90 lar hereinafter.

The mast M is provided at its top with a head or frame 12 carrying sheave wheels 13 over which the hoisting cable 14 of a hopper or bucket 15 is passed. `The bucket 15 is equipped with 95 tvvo pairs of flanged wheels 16 and 17\ so arranged that the lower wheels 16 engage the outer surface of the'mast corner frame members asa trackway while the upper wheelsl'? .engage the inner surface of the same frame members. In ,100 orderto providev for separating the bucket from the mast, the upper Wheels 17 are mounted on yremovable stub shafts 18 which are normally held in place by cotter` pins 19. By removing the cotter pins the stub shafts 18 can be driven 395 outwardly -to release the Wheels 17 so that the bucket can be removed. v

The traveling bucket 15 is provided with a discharge member,` 20 normally closed by a hinged gate 21. A lever device 22 pivoted at 2,3 1.10

entof the present i y on the bucket rim projects at 24 into a position to engage a trip member 25 mounted at 26 on the mast to automatically open the gate 21 and discharge the bucket at any desired point in its upward travel. The trip member 25 is preferably pivotally mounted and is provided with :a shock absorbing spring member 27 to prevent injury or breakage.

An important feature of this arrangement is the provision of a feed chute 28 which is so mounted that it extends directly kthrough the body of the mast M to dischargematerial received from the bucket 15 at the side of the mast opposite to that on which the bucket is mounted. Preferably the feed chute 28 is pivotally mounted at 29 on the mast and is soformcd and balanced that, .through the action ofr gravity, the chute normally tends to take a position, such as is shown in full lines in Figure 1 of the drawings, in which to receive material from the discharge port of the bucket 15.

In order to provide for the travel of the buck'- et without interference with the projecting end of the feedchute, Va pair of curved arms 30, whose y lower extremities engage a stop plate 31 on the mast inthe normal position of the chute, form a pair of cam members adapted to be engaged by theraxle 32v of the lower Wheels? of the bucket to force the chute out of the path of travel of the bucket during itsV passage thereby. As soon as the bucket has passed above the position of vkthe chute,j the chute swings back to its normal position and the bucke-t engages the trip mem ber 25-which causes the gate 21 to open and discharge the contents of 'the hopper into the r'chute. In circumstances where the mast is located closely adjacent the work, the feed chute 28. may discharge'material directly where it is needed; w

i In.' normal operations a further and more ex- -htensi've distribution of the material will be f needed and a delivery and distributing spout 33?Wi1l be required. In order to support the innerf end of the vspout 33 a support or bracket :'34A is mounted' on the mast for vertical adjustjx'r'ientthereon and a universal joint connection 35 is providedv between the bracket and the delivers/spout.

Inorder to support the outer end of the spout 33. a second support or bracket 36 is mounted on'l the mast and a block 37 and tackle connection 38' is provided between the upper bracket 361 and the outer end of the spout. The two bracket members are united into a unitary assembly. through a connecting rod39 thereby forming a slidable frame 47 so that a block and tackle connection 40 between the mast head and theupper bracket 36-may be used with the delivery choring plate42 for guy lines 43.

scent, a stop plate 45 is fitted to thefmastnear "the base thereof and extends laterally beyond `bersf46 of the traveling carriage on which the the sides ofthe mast to receivethe frame membucket is mounted. `In orderto cause the bucket tobe discharged at different elevations in accordance with the progress ofthe work, the mast maybe equipped with openings at diiferent levels to receive the feed chute. The mast will also be equipped with stop plates 31 and with properly related seats for the trip member 25 and to support the chute in the different positions.

The sliding frame 47 having bracket members 34 an 36 connected by rod 39 serves also to provide another function and that is to assist in the erection of extension units on the mast itself. In Figure 4 of the drawings the brackets 34 and 36 are shown as supporting an erecting sparor pole il in a position extended beyond the top of the mast in order to provide for lifting another mast section into position to be iitted at its base to the connecting plates 11.

1f it be found desirable to extend the mast M` .to a greater height after the upper limit of errective distribution ofthe chute 33 is reached, or before operations are begun, the present improvements embody a novel methodl and means for accomplishing this result, wherein the sliding frame 47 forms a part thereof. The base section 10 of they mast may be suitably erectedl and secured in position in any desired manner as for example, by setting up the gin pole 4'1 on the ground, raising the bottom section 10 thereby and setting it in place on the foundation. As seen in Fig. 4, the upper portion of section 10 is ico provided with connecting plates 11 and the 1clock l and tackle connection 40, which latter may be temporarily iixed .in position for permitting ready removal. This section is then temporarily guyed after which the sliding frame 47 comprising connected brackets 34 and 36 are put in place theren l on. The upper bracket 36 is provided with a hole f the bottom of the pole, if desired, but the same is not essential. The entire frame 47 is now adapted for sliding movement along the face oi the section 10, by the block and tackle connection 40. y.The device is now prepared to put in d place another mast section. As the frame and pole serve as the lifting means for `another section, any desired arrangement may be provided The latter may be provided with securing means for f on the pole for supporting or raising the addi V tional section from the ground to its superposed position on the erected section 10.. For example, a block and tackle 50 connection may be suitably secured along the length of or at the top of the pole, whereby the cable thereof mayhave an end secured to the'section on the ground to be raised, with its other end fixed to the groundv orto frame 47 or in the hands of workmen or attached to other power means at the ground.

. The additional mast section is now raised by applying power to the block and tackle connection 40, whence the sliding frame 47, carrying gin pole 41 and said additional mast section are elevated'along the section 10, to a position where said additional mast section is adjacent Vthe top .of section 10, whence the former may be swung over and superposed on the top of section 10, bolted thereto by connecting plates 11, with the top temporarily'guyed. If desired, another methodof carrying out the foregoing operation may be practiced; The frame 47'1nayv be raised along lle section 10, by the block and tackle connection 40 until same is adjacent the upper portion of the mast, at which point the frame 47 may be bolted to the mast for steadying and supporting same. The additional mast section may now be raised from the ground by applying power to the cable of the block and tackle connection 50 on the pole 41, said section being lifted or supported by the pole 41, until the base of said additional section is adjacent the top of erected section 10, whence the former may beswung over and superposed on the top of section 10, bolted thereto by connecting plates l1, with the top temporarily guyed. Previous to the raising of such additional section in practicing either method, said section may be provided at its top with another block and tackle connection 40, or that present on section l() may be secured on the additional section since it is no longer needed to sustain frame 47 after it has been temporarily 'lxed to section 1Q as suggested in the secondly described method.

|Ihe sliding frame 47, carrying brackets 34, 36 and pole 41 may now be lowered to the ground by block and tackle connection 40, whence a third additional section may be elevated along the two sections now erected, until same reaches the top of the mast whence said third section may be superposed on the mast as previously described. When the frame 47 has been bolted to the mast (as in the second described method), said frame 47 may be disconnected from section 10 and raised by block and tackle connection 40, along the face of the now erected additional section to a point near the top thereof where said frame may again be bolted to said additional section. The procedure for raising a third section by this method is the same as that previously described. These methods of erection may be repeated until all intermediate sections and the nal top section are in place. Suitable anchoring plates 42 and guys 43 may be provided throughout the height of the mast as desired.

When the entire mast is erected, the sliding frame 47 may be lowered to the ground and the pole 41 removed, after which said frame 47 and brackets 34 and 36 function to support an adjustably positioned delivery spout, boom or other mechanism desired in the operation of the apparatus. It is therefore apparent that in practicing my methods of erection, the same sliding frame and brackets which later serve in the operation of the mast plant as such, are used to erect same. A double function is therefor derived from the sliding frame 47. The complete rigging is very easy and speedy calling for only the addition of the pole 41 and tackle 50 thereon which is readily added or removed as needed.

It is furthermore notable that after the materials have been distributed throughout the range of the mast plant and it is necessary to move same, thev dismantling of the mast is simply accomplished by practicing the methodsvin a reverse manner. While the unitary assembly 47 has been illustrated in connection with the method of erection, by reason of its adaptability for use in the later operation of distribution, it is understood that the present improvements are not limited thereto, but contemplate any single sliding frame or support as Well, which is adapted to function with the gin pole in the erection process.

Various mcdications within the scope of the present improvements will be apparent to those skilled in the art.

I claim:
